For those who install a WO on your L134 engine, I have a method to get it running right and no special tools are needed. First, you make sure you have a good base gasket and heat insulator under it. Get her attached to your fuel pump, and start the engine. It may not idle, but will run. Check for fuel leaks. If it's not leaking, then you will most likely need to raise the idle speed up by turning in the idle stop screw. Not the mixture screw. Once you have it running, and you warm up the engine, you can begin adjusting it down to a fine tune. I slowly turn out the stop screw until it will just stay running. Then you begin the fuel mixture adjustment. Turn it out and see if the engine picks up speed. If it does, keep turning until no more speed is heard. Then slow it down again by turning out the idle stop screw. Now fine tune the mixture screw. Go back in until it slows and then out until it just picks back up to a nice idle. Stop there. Next you examine throttle responce. If you have no backfire coming out the carb, look down the throat and see how the fuel is coming in as you open up the throttle (step on the gas). There should be a squirt coming from the accelerator pump when you "step on the gas". If not, the leather cup may be dry and not sealing against the round chamber walls inside the float chamber. You also need to note if there is a dead spot when you step on the gas. You may need to set the metering rod also. This will require you to remove the top parts of the WO carburator while on the engine. To do this, first remove the choke link between the choke valve and the throttle base . The funny thing with the slotted arc. Be careful you don't drop the Jesus clip and the small coil spring. Now remove the air horn two large screws. Come straight up with the air horn and don't drop those screws. Set it to the side. You now can view the top of the metering rod. It has a 5/16 inch lock nut. You want the metering rod all the way down in the jet, and the post in the eye of the metering rod touching the top of the eye's hole. What this does is lift the rod, as soon as the throttle or foot petal is used. This is part of the cause of your dead spot. The metering rod must pick up at that moment or no fuel will be let through. The other thing is a squirt of fuel from the accelerator pump must also come into play. It too helps with the dead spot. To seal the pump with the leather cup, I do the following:Remove the top cover from the float chamber. You must disconnect the rod first that comes from the throttle shaft up to the rocker assembly that lifts the metering rod. Don't drop the clips, jesus etc. and the screws and lock washers holding the float chamber lid. You will not enjoy looking for them. Carefully lift the top off. You'll see lots of stuff. metering rod, float, and accelerator pump with leather cup. At the top of the pump is a horseshoe link with Jesus clip. Note how it's hooked up. Go over to a spot where you can work on it without losing anything. Take the horseshoe link off and remove the pump assembly. What you do next is my method. You soak the leather cup in vineager for 5-10 minutes. Not too long!!!!!!!! This will expand the leather and soften it. I also take a very small flat bladed screwdriver and very gently slide it around under the leather lip and over the internal expander spring. Do not break or crack the leather!!!!!!!!! You can test things as you go. First check the fit of the cup in the round hole that has a coil spring sitting in it. At first you will note it doesn't feel tight. It doesn't make a seal and pump gas out the bottom. So, do the soak. You will see it get wider. Not too much! Test it for fit. I also oil the leather before I re-install the pump in the float lid. You will definately notice the cup now sealing. Now put it all back together. Check that the readjusted metering rod is the same as you previously adjusted it. Be very careful going down with the lid that you don't bend or damage the metering rod. It needs to gently go back into the mainjet in the bottom when you install the lid. I think you will now find that your carb has awoken. It wants to work. Your grin will widen and wow, this thing really is nice. This is not a textbook method. Just Oilly's garage hint. Hope this helps you. Scout can lamblast me now. Oilly
